Practice Density, Mass and Volume Questions

1. A piece of tin has a mass of 16.52 g and a volume of 2.26 cm3. What is the density of tin?

• Given• Mass= 16.53g Volume 2.26cm3

• Unknown • D=?

• Equation• D=M/V

• Sub and Solve• D=16.53g/2.26cm3

• D= 7.3g/cm3

• Sentence• The piece of tin that has a mass of 16.52g has a density of 7.3g/cm3

2. A man has a 50.0 cm3 bottle completely filled with 163 g of a slimy green liquid. What is the density of the liquid?• Given

• V=50.0cm3 M=163g

• Unknown• D=?

• Equation• D=M/V

• Sub and Solve• D=163g/50.0cm3

• D=3.26g/cm3

• Sentence• The slimy green liquid has a density 3.3g/cm3

3. A sealed 2500 cm3 flask is full to capacity with 0.36 g of a substance. Determine the density of the substance. Guess if the substance is a gas, a liquid, or a solid.

• Answer 0.000144g/cm3• The sealed flask is a gas

5. The density of pine is generally about 0.5 g/cm3. What is the mass of a 800 cm3 piece of pine?

• Given• D= 0.5g/cm3• V= 800cm3

• Unknown• M=?

• Equation• M=D x V

• Sub and Solve• M =0.5g/cm3 X 800cm3• M=400g

• Sentence• The mass of the pine is 400g

6. What is the volume of 325 g of metal with a density of 9.0 g/cm3?• Given

• M= 325g• D=9.0g/cm3

• Unknown• V=?

• Equation• V=M/D

• Sub and Solve• V= 325g/9.0g/cm3• V=36.1cm3

• Sentence• The volume of the metal is 36.1cm3

• 7. Diamonds have a density of 3.5 g/cm3. How big is a diamond that has a mass of 0.10 g?

• Answer – 0.029cm3

• 9. A graduated cylinder is filled with water to a level of 40.0 mL. When a piece of copper is lowered into the cylinder, the water level rises to 63.4 mL. Find the volume of the copper sample. If the density of the copper is 8.9 g/cm3, what is its mass?
